10mm wide glossy lines near 40/80/10mm from the center of the
first side of duplex printing
[Symptom]
10 mm wide semi-glossy lines [a] and highly glossy lines [b] may occur at one of near 40, 80, and 120 mm from the center on
the first side of duplex printing.
The arrow [c] indicates the direction of feeding.
[Cause]
The secondary fixing assembly separates thin papers by engaging the fixing separation claw [1] to the pressure roller.
a. when the surface of the pressure roller is lightly scratched by the fixing separation claw, glossiness of the area where the fixing
separation claw comes in contact with decreases and 10mm semai-glossy lines occur. The symptom tends to occur easily when
the pressure roller is new.
b. The pressure roller in the secondary fixing assembly may be polluted in some cases due to paper and/or toner scattering inside
the engine. The pollution is cleaned in the area where the fixing separation claw comes in contact with, so the glossiness is higher
compared to the area where the claw does not come in contact with, causing the 10mm wide highly glossy lines to occur.
